  • Publication number: 20130217081
    Abstract: The invention relates to methods for enriching monomer content in a cycloalkane oxidation process mixed organic waste stream. In particular, the methods involve combining a biocatalyst with a mixed organic waste stream from a cycloalkane oxidation process, and enzymatically converting dimeric and/or oligomeric components of said waste stream into monomeric components. The methods may enrich the content of diacids, adipic acid, and/or other ?,?-difunctional C6 alkanes in the mixed organic waste stream. Additionally, the treated mixed organic waste streams may have improved burning efficiency.

  • Publication number: 20130189753
    Abstract: This document describes biochemical pathways for producing butadiene by forming two vinyl groups in a butadiene synthesis substrate. These pathways described herein rely on enzymes such as mevalonate diphosphate decarboxylase, isoprene synthase, and dehydratases for the final enzymatic step.

  • Publication number: 20130183728
    Abstract: This document describes biochemical pathways for producing adipic acid, caprolactam, 6-aminohexanoic acid, hexamethylenediamine or 1,6-hexanediol by forming two terminal functional groups, comprised of carboxyl, amine or hydroxyl groups, in a C6 aliphatic backbone substrate. These pathways, metabolic engineering and cultivation strategies described herein rely on CoA-dependent elongation enzymes or analogues enzymes associated with the carbon storage pathways from polyhydroxyalkanoate accumulating bacteria.

  • Publication number: 20130118143
    Abstract: Composite yarns, comprising one or more elastomeric fibers and hard yarns, are formed by adhering the elastomeric fibers and hard yarns together using a size material. The size-covered composite yarn can be used in weaving and knitting to make stretch fabrics with desired garment characteristics. The size material may be removed by subsequent wet fabric processing.
